The transmit power of a TV satellite is 40 W and the diameter of the parabolic antenna at the transmit antenna is 80 cm. The diameter of the parabolic antenna at the receiver is 120 cm. Distance from the satellite to the earth is 40 000 km, frequency is 11.5 GHz. Given that both antenna efficiencies are equal to nt = nr = 0.7, how many dBm is the signal received by the receive antenna? (Hint the antenna aperture of a parabolic antenna with diameter D is given by (pi × D^2 )/4

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e. g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
